They've been friends for the past six years and made their relationship public last fall at the Country Music Awards. According to RadarOnline, fellow band members Charles Kelley and Hillary Scott were guests at their sunset wedding near Nashville, Tenn.

Looks like music is officially part of their union! In addition to Dave rocking out to his band, Kelli is a Warner Brothers music executive. Apparently he popped the question right before Christmas and spelled out his proposal in holiday lights.Congratulations to the happy couple!
